Problems solved by technology

However, the traditional method of directly adding powdered pigments is still used in coloring, which has two disadvantages: firstly, dry powdered pigments are easy to drift and be inhaled by the human respiratory tract during mixing, polluting the environment and affecting health; secondly, most of the ordinary pigments are in 400 mesh , that is, the particle size is about 38 microns, and the amount of pigments with the same effect is about 10 times that of imported pigments with 1000-1200 mesh and particle size of 10-13 microns, and the price of imported pigments is 20-25 times that of ordinary pigments.

Embodiment Construction

[0006] Percentage by weight, 38% dioctyl phthalate, 30% EVA emulsion, and 32% butyl acetate constitute the pigment carrier, first place the dibutyl phthalate and butyl acetate of the formula in the mixing tank Inside, turn on the mixer, and slowly add FVA emulsion while stirring. When the FVA emulsion is completely dissolved in the solvent and becomes a viscous liquid, it is stored as a pigment carrier for future use.

[0007] Pigment carrier 59%, titanium dioxide 30%, light calcium carbonate 10%, triethanolamine 1%. First, put the pigment carrier of the formula amount in the mixing tank, start the mixer, under the condition of stirring, add titanium dioxide, then add light calcium carbonate, wait for the solid powder to be completely wet, add triethanolamine, and then stir for about half an hour. Grinding by the upper three-roll mill, the fineness reaches 3-5μm, and the finished white color paste is ready;

[0008] 64% of pigment carrier, 18% of carbon black, 17% of light ca...

Abstract

The invention relates to EVA (ethylene-vinyl acetate) pigment color paste. The EVA pigment color paste comprises four major components, namely a pigment carrier, a dispersant, a color-developing pigment and a filling material. The pigment carrier is constituted by dioctyl phthalate, butyl acetate and an FVA (fumarate vinyl acetate) emulsion, the dispersant adopts triethanolamine, the color-developing pigment adopts pigment red, pigment yellow, pigment blue, carbon black and titanium dioxide respectively, and the filling material adopts light calcium carbonate. When the EVA pigment color paste is manufactured, the FVA emulsion is firstly dissolved in dioctyl phthalate and butyl acetate to form a viscous pigment carrier, then one of the color-developing pigment and light calcium carbonate are blended into the pigment carrier, the dispersant is added, full stirring is performed, and then a three-roller grinding machine is used for grinding to the fineness required by the technology, namely the reference color base of the invention.

Description

Technical field: [0001] The invention relates to an EVA pigment color paste, specifically refers to a color-developing raw material used for EVA product processing, and belongs to the technical field of paint chemical industry. Background technique: [0002] EVA resin products have been widely used in all aspects of people's lives. However, the traditional method of directly adding powdered pigments is still used in coloring, which has two disadvantages: firstly, dry powdered pigments are easy to drift and be inhaled by the human respiratory tract during mixing, polluting the environment and affecting health; secondly, most of the ordinary pigments are in 400 mesh , that is, the particle size is about 38 microns, and the amount of pigments with the same effect is about 10 times that of imported pigments with a particle size of 1000 to 1200 microns and a particle size of 10 to 13 microns, and the price of imported pigments is 20 to 25 times that of ordinary pigments.
